Vernonia lindheimeri (Woolly Ironweed) is a showy perennial that thrives where conditions are tough. This resilient plant can handle low fertility soil, dry climates, and resists deer and rabbits. Woolly Ironweed has a gentle upright habit, sturdy stems, and fine fuzzy foliage with an airy texture. Silvery buds open to clusters of bright magenta disc flowers in mid-to-late summer. Blooming for 6 weeks or more, the flowers nourish native bees and other pollinators. A North American native perennial from Texas and Northern Mexico, its common name comes from its iron-like qualities – both durability and seed clusters the color of rust.

Vernonia lindheimeri (Woolly Ironweed) is a showy herbaceous perennial that gets its name from the fuzzy white undersides of its narrow leaves, giving it a natural defense against deer and rabbits. Woolly Ironweed is native to the sunny hillsides and meadows of northern Mexico and Texas. Plant Ironweed in a sunny location in low fertility soil with good drainage. Water as needed to establish, thereafter it is a waterwise, resilient perennial. Over time, it will naturalize gently, but it is not aggressive. Excellent choice for a rock or alpine garden or xeriscape. Plant with Muhlenbergia rigens Undaunted, Solidago, Aster, and Helianthus for a full palette of fall flowers. It also makes lovely cut flowers. Hardy in zones 7-10, leave it standing over winter and cut back to the ground in spring after new growth emerges.
